DOOR-GPERATING MECHANISM.

Application filed September 18, 1916.

To all whom it may concern:

it known that 1, Emmy C. UMPLEBY, a citizen of the United States,residing at Angelica, in the county of Allegany and State of New York,have invented new and useful Improvements in Door-@perating Mechanism,of which the following is a specification.

This invention relates to door operating mechanisms adapted to be usedon the bodies of automobiles and similar vehicles, and it consists inthe novel features hereinafter described and claimed.

An object of the invention is to provide mechanism of the characterstated which is of simple and durable arrangement of parts and whichincludes a manually operable lever adapted to be used for working alatch device and for swinging the door.

Another object of the invention is to provide in a mechanism such asstated, features so arranged that the bolt of the latch device is movedto a retracted position at the initial movement of the mechanism therebyreleasing the door, and the door is swung during the final movement ofthe mechanism. Also provision is made whereby the parts may be set so asto leave thedoor free to be swung without the use of the lever.

In the accompanying drawings Figure 1, is a side view of an automobilewith parts broken away showing the mechanism applied;

Fig. 2, is a fragmentary sectional view of the same showing the dooroperating mechanism in section;

Fig. 3, is a perspective View of the door operating mechanism detachedand showing some of the parts disconnected;

- Fig. A, is a detailed sectional view taken on the line H of Fig. 2.

As illustrated in the accompanying drawings the mechanism is shownapplied to the body of an automobile, but it is to be understood thedevice may be applied and used to advantage on the bodies of other kindsof vehicles.

The vehicle body 1 is provided at its side with the usual door opening 2and a door 3 is arranged to fill in and close the said open ing. Thedoor 3 carries at one side edge arms 4 which are fixed to a verticalshaft 5 journaled in or to the side of the body 1 beyond one edge of thedoor opening 2. A crank 6 is fixed to the lower end of the shaftPatented Apr. 17, 1917.

5 and is located below the floor of the body 1 as best shown in Fig. 2.A keeper 7 is mounted at the free edge of the door 3 and a guide 8 islocated in the stile 9 which delines that edge of the opening 2, whichreceives the free edge of the door3 when the same is moved to a closedposition in the door opening 2. A latch bolt 10, is slidably mounted inthe guide 8 and is provided with a beveled end adapted to enter thekeeper 7 when the door 3 is in a closed position in the door opening 2,whereby the door is secured in closed position.

A bar 11 is pivoted at its upper end to the side of the body 1 at apoint above the guide 8, as indicated at 11 and carries at anintermediate point a pin 12 which is slid ably rcceivecl in a slot 13,provided at the inner end of the bolt 10. A collar 14- is adjustablymounted on the bar 11 and is held at an adjusted position thereon by aset screw 15 in the usual manner. A flat spring 16 is carried by thecollar 14 and bears at its upper portion against a side pin 17 carriedby the bolt 10. The spring 16 is under tension with a tendency tonormally hold the bolt 10 in a projected position in the guide 8., andone end of the slot 13 in contact with the side of the pin 12. The lowerportion of the bar 11 passes through an opening 18 provided in the floorof the body 1.

A rod 19, is pivotally connected at its rear end with the lower end ofthe bar 11 as shown at 19 and at its forward end the rod 19 is pivotallyconnected with the rear end of a rod 20. The rod 20 is provided at apoint adjacent its rear end with a slot 21 which receives the pin 6 ofthe crank 6. A pin 22 passes through the end portion of the crank pin 6which lies below the rod 20 and serves to hold the said rod up inposition on the crank pin.

The forward end of the rod 20 is pivotally connected with a yoke 23, andthe said yoke in turn is pivotally connected with the lower end of ahand lever24. The said lever is fulcrumed upon the floor of the body 1and passes through an opening therein as shown in Fig. 2. A segment 25,is mounted upon the floor of the body adjacent the lever 24: and isprovided at its upper edge with spaced notches 26. A spring pressed pawl27, is slidably mounted on the lever 24: and is adapted to engage in thenotches 26 of the segment 25.

7 lows: With the parts in the positions shown in full lines in Fig. 2,the bolt 10 is in a projected position and its end is received in thekeeper 7 and the door 3 is locked in a closed position. When the pawl 27is withdrawn from the rear notch 26 and the upper end of the lever 24 ismoved in a forward direction to the position shown in dotted lines, therod 20 is moved rearwardly and the slot 21 moves along the crank pin 6without turning the shaft 5. The rod 19, however, moves rearwardlysimultaneously with the rod 26 and swings the lower end of the bar 11rearwardly, whereby the bolt 10 is withdrawn or retracted from thekeeper 7 Thus the door 3-is freed and may be swung by hand and at willfrom a closed to an open position and vice versa. Therefore it will beseen that the initial movement of the lever 72% and the parts connectedtherewith does not move the door 3 but serves merely to move the latchbolt 10 to a retracted position.

. When the upper end of the lever is moved forward to an extent whichwill permit the pawl 27 to enter the forward notch 26, the forward endof the slot 21 comes in contact with the crank pin 6 whereupon the shaft5 is turned and the door 3 is swung from a closed to an open position.

When the upper end of the lever 24L is swung rearwardly the end of thebolt 10 is projected into the path of movement of the keeper 7 and asthe door 3 swings to a closed position, the keeper strikes the beveledend of the bolt 10 and the bolt is moved longitudinally against thepressure of the spring 16, and the slot 13 moves along the pin 12.

When the socket of the keeper comes into alinement with the bolt 10 thelatter is shot forward by the spring 16 and is caused to enter thekeeper, whereby the door 3 is secured in a closed position in the dooropening of the body.

From the foregoing description taken in conjunction with theaccompanying drawings it will be seen that a door operating mechanism ofsimple structural arrange- Inent is provided and that the same may beoperated and controlled by one occupying a forward seat of a vehicle toopen and close a door positioned at the side of the vehicle body at apoint behind the operator's seat.

1. In combination with a body having a door opening, a door mounted forswinging movement at the opening, a latch bolt mounted for movement onthe body and adapted to engage the door, a bar pivoted on the body andhaving a pin and slot connection with the bolt, a spring interposedbetween the bar and bolt, and a lever operated mechanism connected withthe door and the bar 2. In combination with a body having a dooropening, a door mounted for swinging movement at the opening, a latchbolt mounted for movement on the body and adapted to engage the door, abar pivoted on the body and having a pin-and-slot connection with thebolt, a collar adjustably mounted on the bar, a spring carried by thecollar and engaging the bolt, and a lever operated mechanism connectedwith the door and the bar.

In testimony whereof I aliix my signature.
